BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a unit display device for a gamemachine and to a game machine with the unit display device.

2. Description of the Prior Art

Japanese registered utility model No. 3051491discloses a unit displaydevice in which the first variable display 11 having a plurality ofdisplay windows 1 (window part) and the second variable display 12having one window part are installed in the game machine described bythe reference. This display is illustrated in FIG. 1 of the instantapplication.

In this embodiment, the first variable display 11 is a display part(outer) of the pattern of the mechanical display means which is called“Reel (rotating body)”, on the other hand, the second variable display12 located at the right of three reels is a display of the electronicdisplay means which is called “Graphic (video type)”.

This game machine has a character in a controller which is not shown ina figure. In addition, the controller controls to give “Privilege(dividend) by the stopped pattern of the second variable displayregardless of the combination of the pattern of the first variabledisplay 11 (regardless of the prize mode of the first display device).

In reference to this known device, a slot machine is explained as oneexample of the game machine. Generally speaking, the slot machine makesthe three reels, on which several patterns are arranged for instancehorizontally, to rotates independently and the rotating body to stop bypushing the stop button one by one, and the dividend by tokens such asmedals and coin is returned according to the combination of the patternsat a stopping state.

For the combination of this pattern, when one medal turns on, thecombination of one line with three patterns located next to a line L1 ofone medal at the center corresponds among patterns that appears to eachdisplay window (sign 1 of FIG. 1) located behind the front panel of thegame machine; when two medals turn on, three lines including the linesL2 and L3 corresponds; and when three medals turn on, five linesincluding cross lines L4 and L5 corresponds. Therefore, when two or moremedals are turned on, two or more lines judge the possibility of winninga prize of the combination respectively.

By the way, the basis function has the problem that “Prize mode” isuniform because it is only combination of the stop pattern of theplurality of rotating body even though there is a change in a specialwinning-prize including a large bonus, jackpot and the like according tothe combination in the game machine by the combination of the patternsof one display device (first display device) as the conventional slotmachine. In this point, it is the same condition when the first variabledisplay 11 is the electronic display means. There is an advantage thatthe diversity of game can be improved since the first display device 11and second display device 12 are installed in the base plate of the gamemachine in parallel.

However, since the second display device 12 of the is one kind (forinstance, one reel and one display) of device that is located (theposition of the display is fixed) at the player side, it cannot seek thevarious elements of gambling to the second display device 12 in itself.

Japanese published unexamined application Nos. 2004-188159; and2004-290221disclose a unit display device for game machines in which theunit display device 4 is composed of the revolving body which isinstalled in the pair of the bearing member which is not shown in thefigure through the rotary shaft, the bearing member being attachedfixedly to the back of the base plate 2 of the game machine and aplurality of display devices provided at the revolving body integrally.For convenience, these devices are illustrated in FIGS. 2 and 3,respectively, of the instant application.

In addition, in FIG. 3, the reference numeral 4 is a display unit; thereference numeral 7 is a revolving body which is formed in the shape ofa case; the reference numerals 8, 8A, 8B, 9 and 9A are a plurality ofrotating drums (first display device) which are put on the upper surfaceof one side of the revolving body 7 in order; and the reference numeral11 is the wheel-shaped rotating drum (second display device) which isinstalled in the revolving body 7, and the outer circumferential partthereof is seen from an opening 10 located at the center portion of theside face which crosses the upper surface of one side thereof.

Moreover, the 290,221 application describes the use of the unit displaydevice 3 in a game machine described in the 188,159 application. Theinvention described in the 209,221 application includes the unit displaydevice disclosed in the 188,159 application, and it also includes adisplay control device which controls each display device separatelythrough each drive circuit for the first display device and seconddisplay device; means for changing from one display surface in eachdisplay device to the other display surface in each display device; andmeans for deciding preliminarily the contents of the variable display.The display changing means changes the position of the display surfaceby rotating the unit display device based on the approving thepredetermined condition on the game.

However, for the unit display device disclosed in the referenceapplications, the specific composition of the display plate against thepattern display part (variable information), means for supporting thedisplay device, drive source and means for transmitting to change thedisplay device, and means for detecting for the changing position arenot known. In addition, since the game machines disclosed in thereference applications are provided only the unit display device (firstdisplay device) at the casing of the game machine, it is the same as thereference utility model, above, basically when it is focused attentionon the effect of the invention that diversity of the game is improved.

The basic constructional element of the unit display device 35 (seconddisplay device) for the game machine is explained with reference in FIG.5. The reference numeral 36 is a supporting case for the display unit;the reference numeral 37 is a revolving body supported pivotably in thesupporting case 36 through a pair of rotary shafts 38; the referencenumerals 40, 41 are a plurality of display devices which are providedintegrally at the revolving body 37; the reference numeral 42 is a firstattachment bracket which is fixed to one side wall (right wall in thefigure) of the supporting case 36 through suitable attachment means suchas screws; the reference numerals 43 is a drive source (for example,drive motor) which is attached at the outer wall of the supporting case36 through the first attachment bracket 42; the reference numeral 44 afor drive train, transmitting drive power of the drive source 43 to therotary shaft 38; the reference numeral 45 is means for detecting thechanging position (rotating position) of the revolving body 37 by usingthe drive train means; and the reference numeral 46 is means for bearingfor the rotary shaft 38. In this embodiment, the drive source 43 is usedfor changing the display position of the display unit (revolving body37, the plurality of display devices 40, 41 having the display plates).Accordingly, it is different from the drive source for the displaydevices 40, 41. The supporting case 36 for the display unit is fixedsuitably to the second base plate 27 as described above.

In FIG. 5, the reference numeral 36 a is a front opening which iscommunicated with the opening 28 of the second base plate 27; and thereference numeral 36 b is a pair of horizontal slots which are formed ata center part of the side walls and communicate with the front opening.The horizontal slots 36 b extend a predetermined distance toward thecenter part from the front end of the side wall.

The revolving body 37 is installed with a part thereof (about half ofthe revolving body) or full part thereof in the supporting case 36through the slots 36 b with a horizontal, vertical, inclined state ofthe right and left rotary shafts 38 and supporting case 36. In addition,a plurality of small attachment-holes are formed in the supporting case36.

The revolving body 37 includes the rotary shaft 38 and is comprised of apair of facing plates 37 a, a connecting plate 37 b which is attachedfixedly to a center portion of an inner wall surface of the facingplates 37 a and being at right angles to the facing plates 37 a; andsupport plates 37 c and 37 d for the display device 40 and 41 which arefixed to both sides of the connecting plate 37 b at a back-to backstate. The display plate described later is provided to the facingplates 37 a by the intersection of each other.

In addition, an opening is formed at the center portion of the widesupport plate 37 c, and the wheel or a drive source 48 (motor) of thereel-shaped display device 41 is arranged through an attachment frame 47for the drive motor. The motor 48 is a special drive source to vary thepattern display part of the display device 41.

In addition, means 49 for detecting is provided at an outer wall surfaceof the support plate 37 c, the detecting means detecting the rotationalposition of the wheel 41 (display member) of the display device 41. Inaddition, the reference numeral 50 is an output shaft of the drive motor48; the reference numeral 52 is an index member including a fixing platewhich is formed in the shape of a disc, the index member being fixed tothe inner wall surface of the output shaft or the wheel 41 a.

And now, the wheel 41 a includes two pattern display parts P1 and P2.One is defined as the pattern display part P1 as a disc part of thewheel 41, another is defined as the pattern display part P2 as abelt-shaped outer circumferential part which crosses to the disc partP1.

As shown in FIGS. 7 and 8, the patterns are arranged suitably at thedisc part PI and belt-shaped outer circumferential part P2. Therefore,the disc part P1 and belt-shaped outer circumferential part P2correspond the pattern display part (variability information) of thewheel-typed display device 41 of the second display device 35.

On the other hand, a plurality of drive motors which are not shown inthe figure for the reel-shaped display device 40 are attached to thesupport plates 37 d which are located at the back side of the connectingplate 37 d. The outer circumferential part of each reel 40 of thereel-shaped display device 40 corresponds to the pattern display part P.In addition, the detecting means for the position which is not shown inthe figure are arranged at each drive motor as is well known.

In addition, each detecting means is composed of a sensor board, alight-emitting diode, a phototransistor and index member which isattached to the movable member, single or a plurality of the detectingmeans are used according to the kind of the display device. The detailsof the detecting means for the position are omitted.

And now, the plurality of the display devices 40 and 41 are arranged inthe facing plates 37 a through the connecting plate 37 b and supportplates 37 c, 37 d in this embodiment. Therefore, the display devices 40,41 can rotate in the supporting case 36.

In this embodiment, as shown in FIG. 6, the display device 40 is themechanical device having nine reels. In addition, as shown in FIG. 7,the display device 41 is the mechanical device having one wheel 41 a.Therefore, although both display devices 40, 41 are common to themechanical display means, they have the different rotation mode, whichrotate in the opposite direction, so that the various display of thepattern display parts P1 and P2 can be carried out. In addition, one ofthe display devices 40, 41 may be changed to the electronic displaymeans.

In addition, since the belt-shaped outer circumferential part P2 of thewheel-shaped display device 41 is formed in the shape of a curvedsurface, one or more small liquid crystal screens corresponds to thethird display device which is not shown in the figure are arranged atspaces of the belt-shaped outer circumferential part P2. In this case, awindow part which can see the liquid crystal screen is formed at adisplay plate 55.

The drive source 43 is defined as the drive motor in this embodiment. Inaddition, power transmission means 44 having a function of speedreduction in this embodiment is comprised of a small pulley 44 a whichis fixed to the output shaft of the drive motor 43, a large pulley 44 bwhich is provided at a side of the rotary shaft 38 of the revolving body37 and a transmission belt 44 c which is bridged over the small pulley44 a and the large pulley 44 b. In addition, an index member 51, whichis formed in the shape of a ring, is fixed to the outer wall surface ofthe large pulley 44 b through suitable fixing means. The index member 51has a plurality of radial projections 51 a (three projections, forexample), the projections capable of passing through the detectedposition (spaces 1 for example) of the detecting means 45.

In addition, the bearing member 46 is composed of a fixing plate 46 awhich fixed to the outer wall surface of the supporting case 36 so as tocover the horizontal slot 36 b, forming in the shape of a circle orpolygon and ball bearing 46 b which is installed in the fixing plate 46a.

In addition, the drive source 43 may be replaced by a plunger (operatingrod which moves forward and backward in the cylinder) using electricsolenoid or pressure medium. Therefore, the power transmission means mayalso be replaced from a deceleration gear mechanism or power controlmechanism including a control cum, control lever, crank and the like.

The plurality of display plates of the second display device 35 arefixed to the edge portions of the facing plate 37 a of the revolvingbody 37 at a cross state. With reference in FIGS. 5, 6 and 7, eachdisplay plate 55, 56 and 57 of the second display device 35 isexplained.

The display plate of the second display device 35 has three plates eventhough the display devices 40, 41 which compose the second displaydevice 35 have two kinds of devices. That is, the number of the plate islarger than that of the display device 40, 41. The reason comes from thefact that the part of the pattern display parts P1, P2 of the displaydevices 40, 41 can not be seen from one display plate (here, it iscalled “first display plate 55”) of the revolving body 37 depending onthe exchanging position of the revolving body 37 as shown in FIG. 7.

In other words, with reference in FIG. 7, three windows 55 a (opening,for example) are formed at a side of the lower part (one side) of thefirst display plate 55, and the part of the pattern display part P(outer circumferential part) of the three reels 40 a in row of thereel-shaped display device 40 may be seen from the windows. On the otherhand, one window 55 b (opening, for example) is formed at a side of theupper part (another side) of the first display plate 55, and the part ofthe belt-shaped pattern display part P2 of the wheel-shaped displaydevice 41 may be seen from the window.

In addition, in FIG. 8, one window 56 a (opening, for example), which isformed in the shape of a circle, is provided at a center portion of thesecond display plate 56 with a mark, and whole part of the patterndisplay part P1 of the wheel-shaped display device 41 is visible.

In addition, in FIG. 6, nine windows 57 a (openings, for example) areprovided to the third display plate 57 at the matrix state, some partsof the pattern display part (outer circumferential part) of the wholereels 40 a of the reel-shaped display device 40 are seen from eachwindow 57 a.

Therefore, in this embodiment the openings of the first, second andthird display plates, windows including the transparent sheets in thisembodiment are formed with the different shape and numbers according tothe kind of the pattern display part.

with reference in FIGS. 9 and 15, the operation of the display controldevice (CPU) is explained. In FIG. 9, the reference numerals 31, 32 aredefined as input parts; the mark a is an input signal; the referencenumeral 60 is a display control device (includes a display circuit) withmicro computer which processes the input signal a; the reference numeral61 is a memory part which stores necessary information b includinginformation for the prize mode, program, dividend information to operatethe game by the display control device 60; the reference numeral 62 is arandom number generating circuit having a starting point 62 a and stoppoint 62 b; the mark t is a variable time for the pattern display partof the first display device 23 and second display device 35; thereference numeral 63 is some necessary functions for the game (forexample, drawing means for the prize mode, determining means for theprize mode, dividend adding means and the like); the mark c is adetecting signal for a trigger which detects by the detecting means; themark d is a drive signal (trigger) to the drive source 43 forexchanging; the mark e is a drive signal (trigger) to the first displaydevice 23 and second display device 35.

The explanation of the obvious element for functions of each part isomitted. The relativity of the games of the first display device 23 andsecond display device 35 is explained simply.

Then the display control device 60 receives the game-start signal fromthe input part (31, 32) for example, the main game is carried out basedon the program b of the memory part 61. In this embodiment, the maingame is carried out by the first display device 23. Then, the displaycontrol device 60 causes the random number generating circuit 62 toactivate at the same time that the game starts. The part between thestarting point 62 a and stop point 62 b of the random number generatingcircuit 62 is defined as the variable time of the pattern display part25 of the first display device 23. Then, when one of the prize mode (biggame with relatively large amount of dividend) wins a prize by the“flag” in the computer and the drive source (drive motor or drivecircuit) of the first display device 23 stops, the drive signal(trigger) is given to the drive source 43 for moving the displayposition (changing the unit) of the second display device 35. Then, thefact that the player wins a prize is announced to the player through theinforming means and/or lighting system which are not shown in thefigure.

Then, the display control device 60 controls so as to exchange from theposition of one of display plates of the revolving body 37 of the seconddisplay device 35 to the other display plate of the revolving bodyaccording to the “prize mode” which is decided by the first displaydevice 23. For each pattern display part P, P1, P2 of the plurality ofthe display devices 40, 41 of the second display device 35, therevolving body 37 rotates (includes inversion) at a predetermined angle(90 degrees, for example) by one drive source 43 and power transmissionmeans 44 which are provided at the outer wall surface of the supportingcase 36.

Then, the pattern display part appears from the player side at a visiblestate through the display plates 55, 56 and 57 individually installed inthe revolving body 37 against the pattern display part P. P1, and P2 ofeach display devices 40, 41.

In other words, even though the display positions of the units (37, 40,41) change, the pattern display part can be seen definitely from thewindow of either of the display plates 55, 56, 57 at a divided state.

FIGS. 10 to 12 show the illustrative examples of the relativity of thegame between the first display device and second display device. FIG. 10shows the way in which the same patterns line on the cross effectiveline on “prize mode” decided by the first display device 23. In thiscase, the revolving body is switched, and the player can see ninepatterns of the reel-shaped display device 40 through the window of thethird display plate 57.

In addition, FIG. 11 shows the way in which the same patterns line onthe center effective line on “prize mode” decided by the first displaydevice 23. In this case, the revolving body is switches, and the playercan see the part of the pattern display part P of the reel-shapeddisplay device 40 (pattern display part of the three reels in row of thereel-shaped display device in FIG. 10) through the first display plate55 and the part of the pattern display part P2 of the wheel-shapeddisplay device 41 (belt-shaped pattern display part In FIG. 7.

In addition, FIG. 12 shows the condition when “Prize mode” that isdecided in the first display device 23 becomes complete same pattern onan effective line in the vertical direction. In this case, the revolvingbody is changed, and the player can see all of the pattern display partP1 of the wheel-typed display device 41 through the second display plate56.

According to one of the embodiments of “prize mode” shown in FIGS. 10 to12, the display mode of the second display device 35 changes by changingthe display control device 60. In particular, for the display mode showin FIG. 11, it sets the player expectations to win the high prize by thecombination of the pattern display parts P. P2 of the two kinds ofdisplay devices 40, 41.

Then, the explanation of “prize mode” is added. “Prize mode” shown inFIGS. 10 to 12 is only one example. Therefore, “prize mode” is describedas follows:

-   (a) For example, “7”, “7” and “7” line on the effective line.-   (b) For example, “7” segment blinks.-   (c) Specific pattern appears the specific place.-   (d) The plurality of the specific pattern appears the specific place    in parallel.-   (e) It increases the fun of the game that the odds to win a prize    are high compared with the regular game.-   (f) For a bonus, it provides the regular bonus which is relatively    small profit.-   (g) For the bonus, it provides the big bonus which is relatively    large profit.
